Abstract
Pulse height selection affords a method of isolating a moderately narrow range of wavelengths from a spectrum by virtue of energy separation as opposed to wavelength separation as, for example, in crystal dispersion. By use of a proportional counter each incident wavelength is converted into a voltage pulse or rather a pulse distribution, of characteristic pulse amplitude and the function of the pulse height selector is to allow only a specific and chosen range of pulse amplitudes to pass to the scaling circuits. The idealised principle of such a system is illustrated in Fig. 4.1.
